The invention relates to the technical field of ship power, and provides a passive reactor cabin spraying system and a nuclear power ship. The passive reactor cabin spraying system comprises a reactor cabin and a spraying device, and the spraying device is arranged in the reactor cabin; the spraying device comprises a closed type pressure bearing box and a spraying assembly, the spraying assembly communicates with the closed type pressure bearing box, and the closed type pressure bearing box is used for containing cooling liquid and high-pressure gas; under the condition that the pressure in the reactor cabin is greater than or equal to the preset pressure, the spraying assembly sprays cooling liquid towards a reactor system in the reactor cabin under the driving of the high-pressure gas; wherein the preset pressure is smaller than the initial pressure of the closed pressure bearing box. When the temperature and the pressure of a reactor cabin are rapidly increased due to accidents such as water loss of a reactor system, the high-pressure gas provides driving force for the spraying assembly, the resistance of the high-pressure gas and the back pressure of the reactor cabin are overcome, cooling liquid is continuously sprayed to the reactor in the reactor cabin, and the temperature and the pressure in the reactor cabin are rapidly inhibited; human intervention and active equipment investment are not needed, and the safety is high.

    本发明涉及船舶动力技术领域,提供一种非能动堆舱喷淋系统及核动力船舶。非能动堆舱喷淋系统,包括:堆舱和喷淋装置,喷淋装置设于堆舱内;喷淋装置包括闭式承压箱和喷淋组件,喷淋组件与闭式承压箱连通,闭式承压箱用于容纳冷却液和高压气体;在堆舱内的压力大于或等于预设压力的情况下,喷淋组件在高压气体的驱动下朝向堆舱内的反应堆系统喷淋冷却液;其中,预设压力小于闭式承压箱的初始压力。本发明在发生反应堆系统失水等事故导致堆舱温度和压力快速上升时,高压气体为喷淋组件提供驱动力,克服自身阻力和堆舱背压,持续朝向堆舱内的反应堆喷淋冷却液,快速抑制堆舱内的温度和压力;无需人为干预和能动设备投入,安全性高。
